Timer/Event Counter
A timer/event counter (TMR) is implemented in
the microcontroller. The timer/event counter
contains an 8-bit programmable count-up coun-
ter and the clock may come from an external
source or the system clock.
Using the internal system clock, there is only
one reference time-base. The internal clock
source comes from f
SYS
. The external clock in-
put allows the user to count external events,
measure time intervals or pulse widths, or to
generate an accurate time base.
There are 2 registers related to the timer/event
counter;TMR([0DH]),TMRC([0EH]).Twophys-
ical registers are mapped to TMR location; writ-
ing TMR makes the starting value be placed in
the timer/event counter preload register and
reading TMR gets the contents of the timer/event
counter. The TMRC is a timer/event counter con-
trol register, which defines some options.
